Development of a Low-Cost IoT System for Lightning Strike Detection and Location
2019
Lightning and thunder are some of the most violent natural phenomena. They generate a great deal of expenditure and economic loss, especially when they strike in cities. The identification of the concrete geographic area where they strike is of critical importance for emergency services in order to enhance their effectiveness by doing an intensive coverage of the affected area. To achieve this purpose at the city scale, this paper proposes the design, prototype, and validation of a distributed network of Internet of Things (IoT) devices. The IoT devices are empowered with lightning detection capabilities and are synchronized with the other devices in the sensor network. All of them cooperat…
An Overview of 5G Slicing Operational Business Models for Internet of Vehicles, Maritime IoT Applications and Connectivity Solutions
2021
Identification of ecosystems and Business Models (BM) is an important starting point for new complex system development. The definition of actor (or stakeholder) roles and their interactions (at both business and technical levels), together with target scenarios and use cases, provide essential input information for further system requirement collection and architecture specification. The powerful and flexible Fifth Generation (5G) network slicing technology, which is capable of creating virtually isolated and logically parallel networks, enables a large range of complex services and vertical applications. Although various terminologies and models have been proposed in recent years for BMs …

Capturing citizens — Emerging needs: Using social networks in smart cities
2017
In order to reach its objectives, smart cities (or whatever kind of smart urban environment) should be underpinned by complex cyber physical systems (CPS) able to discover needs and services and "smartly" combine them. Services may be thought as services offered by software components, of whatever nature, for instance software, bot, robot, app and so on. Searching for the best service depends on the need of the citizen(s) and also on the type of (smart) environment the citizens are in. Analysis and design of CPSs are more challenging than the only physical or the only cyber system. We propose a design paradigm shift towards runtime for identifying requirements of cyber physical systems for …
The dream of Abha. Note su una ricerca universitaria
2019
Il testo conduce una riflessione sugli esiti della ricerca condotta (in ambito universitario) sull'architettura islamica in Arabia Saudita. Si tratta, anzitutto, di un lavoro di studio e di riconoscimento dei caratteri tradizionali riguardanti lo spazio, il linguaggio, ma anche gli insediamenti che hanno caratterizzato il Paese nella sua storia recente e fino al tempo attuale. Inoltre, a partire dalle condizioni tramandate dalla dalla tradizione, si propone un ragionamento secondo il quale il progetto di architettura interpreta lo sviluppo sostenibile e coerente delle città. Ciò alla luce delle linee strategiche dettate da "Vision 2030", il programma con cui il Principe Salman bin Abdulaziz…
Amman. Il progetto di architettura tra modernità e tradizione
2019
Amman è luogo denso di storia e avido di modernità, confine entropico di culture in cui giordani, iracheni, palestinesi, siriani, insieme esprimono l’anima composita della città. L’odierna struttura insediativa è il frutto dell’espansione realizzata sui resti della Philadelphia romana dall’emiro Abdullah intorno al 1921. In quest’area l’Abdali Urban Regeneretion Project, una grande scommessa di trasformazione urbana avviata sin dal 2013, prevede la costruzione di grattacieli, edifici multifunzionali e commerciali, parchi, con interventi pubblici e privati. Qui, sono sorte negli ultimi anni due importanti architetture: l’Al-Hussein Cultural Center e la Greater Amman Municipality. Proprio in …
Level-Crossing Rate and Average Duration of Fades in Non-Isotropic Hoyt Fading Channels with Applications to Selection Combining Diversity
2015
In this paper, we investigate the second-order statistics of Hoyt fading channels under non isotropic scattering scenarios. Assuming an asymmetrical Doppler power spectral density (PSD), we derive, in the form of single finite-range integrals, expressions for the level-crossing rate (LCR) and average duration of fades (ADF). These new results are then applied to obtain the LCR and ADF of selection combining (SC) diversity over non-isotropic Hoyt channels. In addition to their importance for studying the system performance and characterizing the dynamic behavior of multipath fading channels, the formulas derived are general in that they can be applied to many non-isotropic scattering situati…

Defining Complexity Factors for the Architecture Evaluation Framework
2006
The design and implementation of telecommunication systems is an incremental and iterative process, and system architectures may need to be revised and refined several times during their lifetime. Formal evaluation facilitates the identification of the weak points, where improvements are due in these architectures. In the domain of telecommunications, such evaluation can be based on the Architecture Evaluation Framework (AEF). During the evaluation, a deep understanding of the processes within a system is needed. Meanwhile, the systems being designed are usually complex systems encompassing a large number of components with an intricate pattern of interaction between them. As a result, it i…
